Product Features

1. Structure and Craftsmanship

The machine body features an all-metal integrated structure with high-quality sheet metal spraying, making it resistant to strong impact and vibration.

2. Operation and Display

Digital display, intuitive parameters, push-button operation, timer, and remote control.

3. Air Volume Adjustment

Ten adjustable settings allow precise adjustment of the air volume for higher efficiency, energy saving, and environmental protection.

4. Motor and Impeller

Equipped with a high-performance brushless motor, it offers high speed, low noise, and stable operation, capable of 24-hour continuous operation. The aircraft-grade aluminum turbine impeller provides strong wind power, smooth operation, and low noise.

5.Multi-Layer Filter

This fume extractor adopts a multi - stage tower - type filtration design. It has a 5 - layer filter structure consisting of a fireproof net (to prevent sparks and ensure safety), primary filtration cotton, an H13 filter element, and two layers of activated
carbon filter. This design enables thorough removal of harmful substances, achieving a purification rate of up to 99.97%,
effectively filtering dust particles above 0.3 microns and absorbing toxic gases, smoke, and odour, thus reducing environmental
pollution. (It comes with 5 sheets of primary filtration cotton.)

6. Maintenance and Replacement

The rear access door allows for easy inspection and maintenance, making filter replacement simple and efficient. Each filter element can be replaced individually, effectively extending the life of the main filter element, improving efficiency, and reducing operating costs. Automatic audible and visual alarms are activated when the filter element is clogged.

7.Foam Cotton Sealing

There is foam cotton on the inside of the cover, which not only prevents smoke leakage, but also enhances the air purification effect, and helps reduce noise to ensure a quiet working environment.

8. Movement and Installation

The machine is equipped with silent PU wheels with locking features for easy adjustment and movement. It can be assembled and used in three steps, making installation simple and requiring no specialized technicians.

FAQs

1.What are the core advantages of the KNOKOO FES350F?
The FES350F is a 350W high-power portable fume extractor designed for industrial applications. Driven by a high-performance brushless DC motor, it delivers a massive airflow of 460 m³/h (247 CFM). The biggest highlight is its 4-stage progressive filtration system, achieving a 99.97% purification rate to completely eliminate pungent odors and toxic VOC gases from laser engraving, soldering, and medical beauty treatments. It also features an LCD screen, remote control, and saves up to 45% power compared to similar products.

2.What functions do the control panel and remote control have?
The unit integrates an LCD digital screen for real-time monitoring of the machine's status. Users can adjust the fan speed (multiple levels) , set a timer for shutdown, and check filter status prompts via either the control panel or the infrared remote control, offering highly user-friendly operation.

3.How does it connect to my laser machine or workstation?
The machine standard configuration includes a flexible, self-supporting extraction arm (bamboo tube) that can hover directly over soldering or beauty workstations. If used for an enclosed laser cutter, we can provide connecting hoses and adapters with different diameters (e.g., 75mm or 100mm) to connect directly to your laser machine's exhaust port, ensuring closed negative pressure extraction.

4.How often should the filters be replaced? Are replacements available?
The replacement cycle depends heavily on your workload and processed materials (e.g., engraving acrylic/leather consumes filters much faster than soldering): *Pre-filter: 1 - 3 weeks (highly consumable, recommended to buy in bulk). *Medium Filter: 2 - 3 months. *HEPA Main Filter: 5 - 6 months. *Activated Carbon Filter: 6 - 8 months. *We supply full sets of original replacement filters. We highly recommend purchasing spare filters along with your main machine order to save on international shipping costs.

5.Do you support OEM/ODM customization? What is the MOQ?
Yes! As an original manufacturer, we support customization for voltages (110V/220V, global plug types), private logo labeling (Logo OEM), chassis colors, and specific extraction hose configurations. For standard models, the MOQ is 5 Pcs. For OEM branding customization, please contact our sales manager to discuss specific MOQ and design details.

6.What is the warranty period? How do you handle after-sales service?
We provide a 1-Year Warranty for the KNOKOO FES350F (excluding consumable filters). In case of any mechanical failure under normal use during the warranty period (such as motor or control board issues), we will provide the replacement parts free of charge,while the international shipping cost will be covered by the buyer. One-on-one video technical guidance will also be provided. All units undergo strict quality control tests before factory dispatch to guarantee reliable 24/7 durability.
